11 2010 URBAN WATER MANAGEMENT PLAN Foreword Foreword This Urban Water Management Plan (UWMP) has been prepared by the Calleguas Municipal Water District (CMWD) in compliance with the Urban Water Management Plan Act (UWMP Act) defined in Division 6 Part 2.6 of the California Water Code This act requires municipal water suppliers that serve more than 3,000 customers, or provide more than 3,000 acre feet (ac-ft) of water annually, to prepare UWMPs every five years with the specific deadline of December 31 st of years ending in zero or five. These plans must be submitted to and reviewed by the California Department of Water Resources (DWR). In the past, DWR has issued a guidebook outlining the specific information required by the UWMP Act, as well as the criteria used by DWR staff in reviewing the UWMP for completeness. On November 10, 2009 Senate Bill No. 7 (SB 7) was approved by the Governor and filed with the Security of State. SB 7, also known as the Water Conservation Bill, mandates that the State of California achieve a 20 percent reduction in urban per capita water use by December 31, SB 7 requires each urban retail water supplier to develop water use targets and agricultural water suppliers to implement efficient water management practices. Consequently, beginning in 2010, retail water suppliers must document historical per capita water use in their UWMPs and identify the means and methods for reducing per capita consumption 20 percent by Requirements associated with SB 7 for urban wholesale water suppliers are different than those for urban retail water suppliers. Most notably, since target per capita water use rates will be measured for compliance at the retail level, wholesale water suppliers are not specifically required to identify the per capita water use rates for each of their purveyors. However, wholesale water suppliers are expected to include an assessment of how water conservation programs and policies implemented by the wholesale water agency will help achieve SB 7 requirements. A discussion on preliminary assessments performed for the CMWD service area is included in Chapter 4 of this UWMP. The timing of SB 7 delayed the issuance of DWR s 2010 UWMP Guidebook until early 2011, and as a result, the submittal deadline for 2010 UWMPs has been pushed back to July 1, To meet the July 1, 2011 deadline, activities related to the CMWD 2010 UWMP were performed according to the following schedule Final: 5/12/2011

13 2010 URBAN WATER MANAGEMENT PLAN Chapter 1 Plan Preparation and System Description Chapter 1 Plan Preparation and System Description This UWMP has been prepared for CMWD to meet requirements of the UWMP Act defined in Division 6 Part 2.6 of the California Water Code The intent of this plan is to provide information regarding CMWD s current and future water supplies and water resource needs. Specifically, the UWMP presents water supply planning associated with a 20-year planning period (in 5-year increments), identifies and quantifies adequate water supplies for existing and future demands during normal, dry and drought years, and demonstrates conservation methods and efficient use of urban water supplies. The following summarizes some of the more notable changes made to UWMP reporting requirements since the last issuance in 2005: Retail water suppliers are required to include water use projections for single- and multi-family residential low-income housing. This requirement stems from Section of the Government Code, which requires suppliers to prioritize providing service to housing units that are affordable to lower income households (Water Code ). Assembly Bill 1420 (AB 1420) was enacted, which requires DWR and other State agencies to condition water management grants and loans to urban water suppliers based on implementation of demand management measures, and specifically requires urban water suppliers to submit self-certification statements. SB 7 was enacted, which seeks to reduce state-wide water use by 20 percent by year 2020, specifically requires retail water providers to include the following information in their 2010 UWMPs: 1) baseline daily per capita water use; 2) urban water use targets; 3) interim water use targets; and 4) compliance daily per capita water use. Retail and wholesale urban water suppliers must comply with AB 1420 if they intend to pursue grants or loans from State agencies. Retail water agencies have primary responsibility for meeting SB 7 and the new low-income housing requirements. Present and future measures that can be implemented by CMWD to assist its purveyors in meeting these objectives are identified in this UWMP Final: 5/12/2011

15 2010 URBAN WATER MANAGEMENT PLAN Chapter 1 Plan Preparation and System Description To improve the readability of this UWMP, the document has been organized differently than the structure laid out in DWR s 2010 UWMP Guidebook. Appendix A lists the required elements as defined in DWR s guidance manual and references the section where that topic can be found within this report. To minimize reporting redundancy, water management activities undertaken by CMWD s purveyors are not discussed in detail in this document, as they are addressed in the individual UWMPs of those purveyors. A. Background CMWD is an enterprise special district that was formed by the voters of southern Ventura County in 1953 for the purpose of providing a safe, reliable water supply. Named for the watershed in which it is located, the district is a public agency established under the Municipal Water District Act of It is governed by a five-member board of directors elected by voters to represent each of the five geographic divisions within the District. In 1960, CMWD became a member agency of MWD, which provides wholesale water from the Colorado River via the Colorado Aqueduct and from northern California via the State Water Project (SWP). MWD is comprised of 26 member agencies, and CMWD is the fifth largest member agency in terms of average annual water deliveries. CMWD distributes high quality drinking water on a wholesale basis to 19 local purveyors, who in turn deliver water to area residents, businesses, and agricultural customers. These purveyors are listed in Table 1-2. Approximately three-quarters of Ventura County residents (roughly 630,000 people) depend on CMWD for all or part of their water, and the water supplied by CMWD currently represents approximately 73 percent of the total municipal and industrial water demand within its service area. It is important to note that a large portion of the water use in Ventura County is for agricultural purposes. Agricultural demands are generally met by other agencies or private entities using untreated surface water, recycled wastewater, and groundwater from various basins underlying the area Final: 5/12/2011

In 2008, Newbury Park Academy Water Company was absorbed by California American Water Company. Capehart Housing has transitioned service to the City of Camarillo. Therefore, water demands for Capehart Housing were incorporated into Camarillo s projections for this 2010 UWMP. The Solano Verde Mutual Water Company became a CMWD purveyor in Southern California Water Company changed its name to Golden State Water Company. Figure 1-1 shows CMWD s service area and purveyor boundaries. CMWD s service area encompasses approximately 375 square miles. Land use in the area is primarily residential, commercial, industrial, and irrigated cropland. Note that the City of Oxnard provides water to the Port Hueneme Water Agency (PHWA), which provides water to the City of Port Hueneme, Naval Base Ventura County Port Hueneme and Point Mugu, and the Channel Islands Beach Community Services District Final: 5/12/2011

19 2010 URBAN WATER MANAGEMENT PLAN Chapter 1 Plan Preparation and System Description B. Demographics Two data sources were utilized to develop population, dwelling unit and employment projections for CMWD s service area. These sources include: Southern California Association of Governments (SCAG), Ventura Council of Regional Governments (VCOG), Demographic projections through 2035 were developed by SCAG in This data is available in geographic information system (GIS) format with information distributed by traffic analysis zones (TAZs). This information was utilized by MWD to develop demographic projections for CMWD s service area. The most recent demographic projections available from VCOG were developed in VCOG projections for the CMWD service area were estimated as the sum of the growth and non-growth portions of the following areas: Camarillo, Las Posas, Moorpark, Oak Park, Oxnard, Port Hueneme (including Channel Islands Beach and the Naval Base), Simi Valley, and Thousand Oaks. These areas are located within CMWD s service area. The following sections summarize the demographic projections from each of these sources. 1.

Projections for 2030 and 2035 were not available. MWD s employment projections shown in Table 1-5 are on average approximately 10.5 percent less than those projected in the 2005 UWMP. Based on discussions with MWD, the 2010 UWMP projections assume less growth in manufacturing type businesses and a shift towards businesses in the service industry. As discussed in more detail in Chapter 3, these two changes in employment projections have impacts on MWD s projections for water demands in the CMWD service area. C. Climate Like many regions in coastal southern California, the climate in Ventura County varies based on proximity to the ocean. Areas closest to the coast experience mild summers and winters, while inland areas experience similar winters but warmer summers. In the summer, high temperatures average 75 degrees Fahrenheit ( F) along the coast and 84 degrees further inland. Average winter low temperatures are fairly consistent across the region at 44 to 45 degrees F. CMWD s service area receives an average of 10 to 14 inches of precipitation annually with the majority of this rainfall occurring during the winter Final: 5/12/2011

35 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality Chapter 2 Water Supplies and Quality Southern California s water supply is subject to natural and man-made forces, ranging from drought and earthquakes to environmental regulations and water rights determinations. Some of the challenges facing Southern California with respect to water include: Population and resulting urban water demands are increasing. A major earthquake could damage the California Aqueduct or the Colorado River Aqueduct (CRA), or both, interrupting water supply to the region for up to six months. Water demands associated with environmental causes are increasing, especially in the San Francisco Bay/Sacramento-San Joaquin Bay Delta (Bay-Delta), thus reducing the availability of water for Southern California. New and increasingly stringent drinking water standards are being promulgated and could further impact the use of local surface and groundwater supplies. California, like much of the west, is susceptible to long periods of drought. Recent climate change studies indicate that Bay-Delta and Colorado River supplies could be even more variable than that of the historical record, further stressing California water supplies. Several of the groundwater basins within CMWD s service area are in an overdraft condition. The economic vitality of Ventura County is contingent upon a dependable water supply. Therefore, it is imperative that a strategy be developed to ensure reliable sources of water supply, including using existing supplies efficiently. This chapter discusses both imported and local supplies of water available to CMWD, as well as the water quality associated with each type of supply Final: 5/12/2011

36 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality A. Imported Water Due to the geographic location of its service area, CMWD receives SWP water exclusively under normal MWD operating conditions. The SWP is a 600 mile network of reservoirs, aqueducts, and pumping facilities that convey water from the northern Sierra Nevada Mountain Range to Southern California. Water is treated by MWD at the Joseph Jensen Filtration Plant in Granada Hills and is delivered to CMWD through MWD s West Valley Feeder No. 2 Pipeline. CMWD s sole connection to MWD is located in the City of Chatsworth at CMWD s East Portal Facility. From this point, water is conveyed 1.39 miles through the Perliter Tunnel into Simi Valley, where it is distributed through CMWD s transmission system, injected into the Las Posas aquifer, or stored in Lake Bard. Water stored in Lake Bard is treated at the Lake Bard Water Treatment Plant (WTP), which has a treatment capacity of 65 million gallons per day (mgd), (100 cubic feet per second [cfs]). The WTP is used during the summer months to supplement imported MWD deliveries to the western part of CMWD s service area, and can supply the entire system for short durations if service from MWD is interrupted or reduced due to routine maintenance or emergency. 1. Water Quantity Challenges The original SWP facilities, completed in the early 1970s, were designed to meet the needs of the SWP contractors established at that time. It was anticipated that additional SWP facilities would be constructed over time to meet increases in contractor delivery needs. However, these additional facilities were repeatedly deferred and public attitudes and environmental regulations have changed. As a result, the SWP is not capable of delivering full contractor entitlements every year. The focal point of SWP supplies is the Bay-Delta; the largest estuary on the west coast through which 60 percent of the freshwater used in the State must pass. Years of environmental neglect to this area and political gridlock has resulted in significant environmental damage. In recent years, the Delta smelt, winter-run Chinook salmon, spring-run Chinook salmon, and splittail were added as threatened or endangered species under the federal Endangered Species Act (ESA). Resulting actions taken to protect the ecosystem of the Bay-Delta have placed additional restrictions on SWP operations Final: 5/12/2011

37 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality As mentioned previously, CMWD s sole connection to MWD is the West Valley Feeder No. 2 Pipeline. The West Valley Feeder No. 2 Pipeline is capable of delivering up to 300 cfs of water to the East Portal of the Perliter Tunnel. The reliability of MWD s supply is evaluated in Chapter 5 and contingency planning is discussed in Chapter Water Quality Challenges SWP water is generally of high quality. Total dissolved solids (TDS) concentrations range between 250 and 350 milligrams per liter (mg/l). The quality of SWP water as a drinking water source is affected by a number of factors, most notably seawater intrusion and agricultural drainage from peat soil islands in the Bay-Delta. The water quality parameters of most concern are total organic carbon (TOC), bromide, and salinity. Levels of TOC and bromide in the water increase significantly as it moves through the Bay-Delta. These constituents can combine with chemicals used in the water treatment process to form disinfection byproducts that are carcinogenic. Treated wastewater discharged from cities and towns surrounding the Bay-Delta also add salts and pathogens to the water, which affect its suitability for drinking and recycling. Moreover, actions to protect Bay-Delta fisheries have exacerbated existing water quality problems by forcing SWP diversions to shift from the spring to the fall, when salinity and bromide levels are highest. Closure of the Delta Cross Channel gates to protect migrating fish has also degraded the quality of SWP supplies by reducing the flow of higher quality Sacramento River water. B. Groundwater Groundwater has been used in Ventura County for many years, primarily for irrigation, but also for municipal and industrial water supply. Historically, the aquifer system in southern Ventura County has been in a state of overdraft, mostly in the Lower Aquifer System (LAS), which has led to seawater intrusion. The non-consumptive portion of imported water utilized by the majority of CMWD purveyor customers is treated at local wastewater treatment facilities and discharged to the Calleguas Creek watershed. This water ultimately percolates into the Upper Aquifer System (UAS), increasing groundwater levels in the region. Unfortunately, water in the UAS can have elevated levels of chlorides and TDS.

38 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality is an active participant in regional efforts to put some of this water to beneficial use by advancing groundwater desalter projects (groundwater recovery). 1. Fox Canyon Groundwater Management Agency The Fox Canyon Groundwater Management Agency (FCGMA) is an independent special agency created in 1983 to oversee Ventura County s groundwater resources. The primary objective of the FCGMA is to preserve groundwater resources for agricultural, municipal and industrial uses in the best interests of the public and for the common benefit of all water users. Protection of water quality and quantity, along with maintenance of long-term water supply, is part of that objective (FCGMA, 2007 Update to the FCGMA Groundwater Management Plan, 2007). FCGMA s boundary is located partially within CMWD s service area and overlies approximately 118,000 acres. The FCGMA boundary encompasses the coastal basins that underlie the cities of Oxnard, Port Hueneme, Camarillo and Moorpark. Private groundwater pumping (by non-cmwd purveyors) that occurs within CMWD s service area but outside of FCGMA s boundary is not monitored by a management agency, and therefore, pumping records are not available. There are seven major groundwater basins within FCGMA s jurisdiction. These include the Oxnard Plain, the Oxnard Plain Forebay, the Pleasant Valley, the portion of the Santa Rosa basin west of the Bailey fault and the East, West and South Las Posas Basins. These basins generally contain two major aquifer systems, the UAS and LAS. The aquifers are recharged by infiltration of streamflow and precipitation, artificial and mountain-front recharge, return flow from agricultural and residential irrigation, and in varying degrees by groundwater underflow from adjacent basins. Table 2-1 lists the pumping allocations associated with each of the basins managed by FCGMA. It is important to note that actual pumping can vary from allocation amounts because agricultural users are not governed by allocations if they can demonstrate that they are irrigating efficiently. It is also important to note that not all of the allocations shown in Table 2-1 are allocated to CMWD purveyors. In fact, a majority of the allocations listed in Table 2-1 are owned by agricultural water users (and to a lesser extent municipal and industrial water users) that are outside the CMWD service area. A more detailed accounting of groundwater supplies available to CMWD purveyors is included in the UWMPs for each purveyor Final: 5/12/2011

FCGMA s goal is to balance the groundwater supply and demand within its jurisdiction by To achieve this goal, FCGMA has adopted a number of ordinances in an effort to eliminate groundwater overdraft, and to combat the ongoing threat of seawater intrusion in both the UAS and LAS. These ordinances and resolutions help to regulate, conserve, and manage the use and extraction of groundwater within the region. The most recent relevant FCGMA ordinances are provided in Appendix B Final: 5/12/2011

40 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality 2. Groundwater Storage Strategies and Transfer Agreements In addition to local groundwater supplies used directly by CMWD purveyors, CMWD has incorporated groundwater storage strategies and transfer agreements into its water resources portfolio.. Beginning in the early 1990s, CMWD has periodically stored water through in-lieu means. Under this storage method, CMWD has supplied imported water to well operators which, in turn, reduce groundwater pumping. The reduction in pumping results in the creation of storage credits. Such storage credits are then transferred to CMWD. In this way, groundwater can be stored and subsequently pumped during periods when imported supplies are curtailed. In addition to storing water via in-lieu deliveries, CMWD operates the Las Posas ASR facilities. The project includes dual-purpose extraction and injection wells in two well fields in the Las Posas groundwater basin. CMWD can store water in this basin for use during scheduled shutdowns or emergencies.. Moreover, CMWD has accumulated additional groundwater storage credits through the Conejo Creek Diversion Project (CCDP). The CCDP consists of a diversion structure and pipelines that were jointly constructed by CMWD and the Camrosa Water District. The facilities are owned and operated by CMWD and Camrosa Water District. Recycled wastewater from the City of Thousand Oaks is diverted from Conejo Creek and used for agricultural and landscape irrigation within Camrosa Water District s service area. Water that is not used within the Camrosa Water District is provided to the Pleasant Valley County Water District for agricultural irrigation in-lieu of groundwater pumping. In return, CMWD receives groundwater credits from FCGMA equal to the amount of water delivered. By agreement, those credits are pumped from wells operated by the United Water Conservation District (UWCD) to meet demands in the Cities of Oxnard and Port Hueneme. Figure 2-1 shows CMWD s Accumulated Groundwater Storage Credits in FCGMA-approved programs stored in basins throughout the CMWD service area since Some of this water was directly injected into the Las Posas Well Field. However, the majority represents credits gained from in-lieu deliveries. As illustrated on Figure 2-1, CMWD s groundwater storage steadily increased through However, as a result of drought conditions, CMWD extracted stored water to help meet regional water demands from 2008 through Final: 5/12/2011

Groundwater Quality Table 2-2 summarizes the groundwater quality for the basins that underlie CMWD s service area. Groundwater in CMWD s service area is generally high in TDS and occasionally high in nitrate concentrations. It is important to note that water quality within the basins can vary based on the location of the sample well, condition of the sample well, and groundwater conditions on the day the sample is taken.

Seawater intrusion has long been a concern and was the issue that precipitated the creation of the FCGMA. The intrusion occurs exclusively along the coastline in the Oxnard Plain Basin. Chloride has also become a problem in the East and South Las Posas basins and groundwater from these basins must be blended with lower-chloride water to be suitable for irrigation. This problem appears to have migrated Final: 5/12/2011

44 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality downstream, with some of the City of Camarillo s wells now affected (FCGMA, 2007 Update to the FCGMA Groundwater Management Plan, 2007). High nitrate concentrations in the groundwater is a problem localized in the Oxnard Plain and Forebay basins. Drinking water wells in the impacted areas are often affected during and following dry periods. The primary sources of nitrate are septic systems and agricultural fertilizer. To address the problem, septic systems are now prohibited in the Oxnard Plain Forebay and best management practices (BMPs) are being implemented to limit agricultural contributions. C. Recycled Wastewater CMWD does not treat any wastewater. However, seven service providers treat wastewater that originates within CMWD s service area, as shown on Figure 2-2. These service providers are independent of CMWD and therefore, the entire service area of each provider may or may not be within CMWD s service area boundary. Many of these service providers treat wastewater so that it can be recycled for non-potable uses such as irrigation of golf courses, street medians, and school athletic fields, and dust abatement. Table 2-3 summarizes the recycling efforts of these wastewater service providers, including level of treatment provided, disposal method for non-recycled wastewater effluent, uses of recycled wastewater, and methods currently utilized to encourage recycled wastewater use. Details regarding local recycled water projects within the CMWD service area are provided in Section F of this chapter. Although CMWD does not operate any wastewater treatment facilities, it does own and operate some recycled water pipelines and pumping facilities. CMWD purchases recycled water from Triunfo Sanitation District and the City of Simi Valley and delivers the water to a limited number of customers for irrigation. Additionally, CMWD supports the use of recycled wastewater as a financial participant in the CCDP Final: 5/12/2011

53 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality D. Projected Water Supplies Water supply projections were developed for both imported water and local supplies. Local supplies include untreated surface water, groundwater and recycled wastewater. Water supply projections were projected for three hydrologic scenarios; average year, dry year, and multiple dry years. The average year is the expected demand under average hydrologic conditions (based on historic average year conditions from 1922 through 2008); the dry year is the expected demand under the single driest hydrologic year (based on conditions experienced in 1977); and the multiple dry year is the expected demand during a period of three consecutive dry years (based on conditions experienced from 1990 through 1992). 1. Imported Supply Projections MWD utilizes a custom computer program called MWD-MAIN to forecast demand conditions throughout the MWD service area. MWD projects the need for imported supplies as a function of the demand forecasts and local supplies available to its member agencies. Table 2-6 lists the quantity of water that MWD estimates will be available to CMWD during average, dry and multiple dry year scenarios. Potential quantities of reserves are discussed in more detail in Chapter 5.

(2) CMWD local supply projections differ to MWD projections because CMWD purveyors typically include future local supplies in their projections upon completion of feasibility studies. CMWD also develops local supply projections for its service area. Although MWD and CMWD share information related to existing and future local supply projections, the two projections make different assumptions related to local supply reliability and the likelihood of reality of future supplies. Tables 2-8 through 2-10 list CMWD s local supply projections by source for each hydrologic condition.

(2) Recycled wastewater purchased from Triunfo and Simi Valley and delivered for irrigation. CMWD s local supply projections are substantially higher than MWD s. However, both MWD and CWMD project an increase in imported and local supplies through the planning period. The lower local supply projections by MWD are related to MWD s policy not to include future local supply projects until funding allocations, engineering, environmental approvals, and permitting requirements are substantially complete. CMWD purveyors, however, typically include future local supplies in their projections upon completion of feasibility studies. The following sections provide information on regional and local supply programs. E. Regional Water Supply Programs MWD adopted its first Integrated Resources Plan (IRP) in 1996, as a result of the drought. The 1996 IRP focused on increasing regional supply reliability by implementation of a diverse portfolio of resource investments and conservation measures The 1996 IRP objective was to balance demand management and supply augmentation as well as local resources and imported supplies. Approximately every five years, MWD updates their IRP, which presents in detail the most recent supply augmentation and demand management programs being considered or implemented by MWD. The most current IRP was published Final: 5/12/2011

57 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality in the fall of The 2010 IRP focuses on adaptive management planning recognizing there is significant uncertainty in long-term water supply planning. A summary of MWD s efforts to develop new and alternative regional water supplies is provided below. For more detailed information on MWD water supply planning see the MWD 2010 IRP and MWD 2010 RUWMP. 1. Recycling MWD and its member agencies are widely recognized as leaders in water recycling. It is estimated that over 1 million ac-ft of recycled water was beneficially used within the MWD service area between 1985 and July As part of the 2010 IRP efforts, MWD assembled a technical workgroup focused on evaluating the potential for additional recycled water use. Although the workgroup noted several technical, financial, regulatory and public acceptance challenges associated with significant expansions of recycled water programs, numerous concepts to overcome these challenges were also identified. For the 2010 IRP planning period, recycled water supplies are anticipated to increase in the MWD service area from 353,000 to 430,000 ac-ft per year between 2010 and Seawater Desalination MWD created the Seawater Desalination Program (SDP) in 2000, which included a target of 150,000 ac-ft per year of seawater desalination by A technical committee was formed as part of the MWD 2010 IRP to assess the current status of the SDP and refine seawater desalination supply projections. As stated in the 2010 IRP technical issues paper on seawater desalination, four seawater desalination projects are either currently operating pilot studies or under construction of the full scale facilities. At full scale, these four projects could produce between 130,000 and 143,000 ac-ft per year of renewable supplies. Three additional projects that are not part of the SDP but are within the MWD service area are also in various stages of study or permitting. 3. Competitive Local Resources Program The primary goal of MWD s Competitive Local Resources Program (LRP) is to financially support the development of cost-effective water recycling and groundwater recovery projects that reduce demand for imported supplies. Specifically, for projects that meet the selection criteria, incentives of up to $ Final: 5/12/2011

58 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality per acre-foot per year are possible for up to 25 years. In 2009, LRP water projects produced about 155,000 ac-ft per year. The MWD 2010 IRP indicates a goal of expanding LRP supplies by an additional 174,000 ac-ft per year by Surface and Groundwater Storage Programs Diamond Valley Lake was constructed in 1999 and holds 800,000 ac-ft of water. This water is stored for use during dry year and emergency conditions. In addition, MWD has operational control of approximately 219,000 ac-ft of water in reservoirs at the southern terminals of the California Aqueduct, which provide greater flexibility in handling supply shortages. MWD also delivers replenishment water to member agencies. The member agency in turn delivers this water in-lieu of utilizing water from local sources. The deferred local production allows water to be left in local storage for future use. MWD also delivers water to spreading sites and injection wells for groundwater replenishment. These programs increase supply availability and improve MWD s operational flexibility, thus allowing it to better manage out-ofregion supply and storage programs to meet dry year needs. MWD has an agreement with CMWD to store up to 210,000 ac-ft of water in the North Las Posas Groundwater Basin for ASR. MWD manages other conjunctive use projects that further increase MWD s supply reliability. 5. Central Valley Transfer and Storage Programs MWD has several Central Valley Project (CVP) and SWP transfer and storage programs in place or under development. The agencies involved in these programs include (but may not limited to) Semitropic Water Storage District, Arvin-Edison Water Storage District, San Bernardino Valley Municipal Water District, Kern-Delta Water District, and Mojave Storage Program. These programs are expected to provide approximately 396,000 ac-ft of dry-year water supply. 6. Colorado River Aqueduct MWD is in the planning process or has implemented several programs related to the CRA with the primary objective of having a full CRA during dry years. Some of these programs include: Final: 5/12/2011

59 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality A conservation agreement between MWD and the Imperial Irrigation District, which guarantees MWD at least 85,000 ac-ft of water per year. The Coachella and All-American Canal Lining Projects, which are expected to conserve 26,000 and 67,700 ac-ft of water per year, respectively. A 35-year land management, crop rotation, and water supply program with the Palo Verde Irrigation District that is estimated to conserve up to 111,000 ac-ft of water per year, when the program is fully implemented. Groundwater storage programs along the CRA that could eventually allow approximately 400,000 ac-ft of CRA water to be stored in adjacent groundwater basins for future withdrawal. Collaborative projects with other Colorado River water users such as the Lake Mead Intentionally Created Surplus Storage Program, Drop 2 Storage and Reservoir Project, and the Lower Colorado Supply Project. 7. State Water Project MWD is committed to restoring traditional supply from the SWP through short, mid, and long-term action plans. A summary of these actions are provided below. Short-Term Actions Secure ESA take authorizations. Enhance Delta Smelt habitat. Complete the Bay-Delta Conservation Plan (BDCP) Environmental Impact Statement (EIS). Restore ecosystems.

60 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality Long-Term Actions Restore ecosystems. Implement water supply conveyance improvement projections. Develop storage. Additional information on the status of these actions can be found on MWD and DWR websites. F. Local Supply Programs CMWD has focused its planning efforts on using existing supplies more efficiently and maximizing local water resources. Working cooperatively with local agencies, CMWD supports a number of local recycling and groundwater recovery projects to offset increasing imported water demands. The projects described below and summarized in Table 2-11 include a combination of wastewater reclamation, brackish groundwater recovery, and regional salinity management programs. It is important to note that the effect of each of these projects on groundwater resources and environmental compliance must be evaluated and approved before they can be implemented.

61 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality 1. Regional Recycling Projects CMWD is working with local agencies to implement various water recycling projects. As discussed previously, recycled wastewater is used for beneficial use applications including agricultural and non-agricultural irrigation, industrial use, and groundwater recharge. a. Camarillo Recycled Water A portion of the treated effluent from the Camarillo WRP is pumped to Smith Ranch for irrigation of non-food crops. Approximately 500 ac-ft per year of recycled water are projected to be beneficially used in 2015 and beyond. In addition, the Camarillo Sanitary District has agreements with the Camrosa Water District that allow for delivery of tertiary treated recycled water to Camrosa. b. Camrosa Water District Recycled Water The Camrosa Water District is involved in three recycled water projects: the Camrosa WRF, the Camarillo Water Reclamation Plant and the CCDP. The Camrosa WRF treats wastewater to tertiary levels and then distributes it through a recycled water distribution system for use in landscape irrigation. Approximately 980 ac-ft per year of recycled water are projected to be beneficially used from the CWRF in 2010 with that amount increasing to 2,000 ac-ft per year by The Camrosa Water District and the Camarillo Sanitary District have entered into an agreement to allow for delivery of tertiary treated wastewater to Camrosa from Camarillo. As previously explained, Camrosa also receives recycled water from the CCDP. When Camrosa cannot use all of the CCDP water, it is delivered to Pleasant Valley County Water District in exchange for groundwater credits. The groundwater is pumped by United Water Conservation District for use by Oxnard and Port Hueneme as a local supply. c. Lake Sherwood / Oak Park Recycled Water The Triunfo Sanitation District/Las Virgenes Municipal Water District jointly own and operate the Tapia WRF. Approximately 1,450 ac-ft per year of recycled water produced from this facility is imported into the CMWD service area and distributed to recycled water customers in Lake Sherwood, Oak Park and North Ranch through agreements between CMWD, Triunfo and Las Virgenes Final: 5/12/2011

62 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality d. Oxnard GREAT Program The City of Oxnard is implementing the GREAT Program, which includes an AWPF consisting of reverse osmosis and advanced oxidation. A portion of the flow from the AWPF will be distributed to meet water demands for irrigation and industrial processes. Approximately 2,700 ac-ft per year of recycled water from the GREAT Program is projected to be directly used as recycled water by 2015, with that amount increasing to approximately 7,000 ac-ft per year by e. Simi Valley Water Quality Control Plant The Simi Valley Water Quality Control Plant treats wastewater to tertiary standards. The majority of the water is discharged to the Arroyo Simi, however between 60 and 100 ac-ft per year is used for dust control and irrigation at the Simi Valley landfill. The water discharged to the Arroyo Simi ultimately recharges downstream groundwater basins. Pending regulatory approvals, this water could be available to other downstream CMWD purveyors who could capture the water with groundwater extraction and treatment systems. f. VCWWD No. 1 Reclaimed Water Distribution System Expansion The Moorpark WWTP is operated by VCWWD No. 1. Effluent from this facility is treated to secondary standards and discharged to percolation ponds, the Arroyo Las Posas, or treated to tertiary levels and used for reclaimed purposes. Recycled water is currently delivered to the Moorpark Country Club Estate for golf course irrigation and to local agricultural interests. Approximately 500 ac-ft per year of recycled water are projected to be beneficially used in 2010 with that amount increasing to 1,100 ac-ft per year by Calleguas Salinity Management Pipeline CMWD, working with other agencies and stakeholders, initiated the Salinity Management Pipeline (SMP). Currently under construction, the SMP consists of a pipeline system to collect treated wastewater and brine concentrates from municipal WWTPs, groundwater treatment facilities (both municipal and agricultural), and industrial operations located within the Calleguas Creek watershed. Water discharged into the SMP will be conveyed to other areas where is can be utilized by agricultural users and possibly for wetland applications. Any remaining water will be discharged into the ocean through an ocean outfall. Operation of the facilities will allow for the use of poor quality Final: 5/12/2011

63 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality water that was previously underutilized and will substantially reduce the amount of salts released into the watershed. Over time, this will reduce salt concentrations in surface water and groundwater within the watershed. The alignment of the SMP has been strategically located so that it can receive reverse osmosis concentrate from future brackish groundwater recovery facilities as well as effluent from wastewater treatment facilities. Providing a means for disposal of brine waste from the proposed groundwater recovery facilities allows for increased use of a previously underutilized water supply and could ultimately remove an estimated 42,300 tons per year of salt from the watershed. The following sections provide descriptions of anticipated future brackish groundwater recovery projects. 3. Brackish Groundwater Recovery Projects Water imported by CMWD and delivered to CMWD purveyors that is not fully consumed is collected in local sanitary systems and treated at the local wastewater treatment facilities listed in Table 2-4. There are numerous locations within the Calleguas Creek watershed where discharged treated wastewater recharges the local groundwater basins. Much of this groundwater has relatively high dissolved solids and chloride concentrations, which requires that the water be treated with reverse osmosis. The primary purpose of the brackish groundwater recovery projects is to recover this groundwater of poor water quality, thereby increasing the availability and reliability of the region s local water supply. a. Round Mountain Desalter Groundwater levels in a local perched aquifer near CSUCI, east of the Bailey fault in have been rising for decades and Camrosa Water District plans to construct the Round Mountain Desalter to treat local brackish groundwater using reverse osmosis. Groundwater to be treated at the Round Mountain Desalter will be pumped from an existing well on California State University Channel Islands (CSUCI) property in Camarillo. The Round Mountain Desalter will produce about 1,000 ac-ft per year of potable water. b. Camarillo Desalter Similar to the Moorpark Desalter, the Camarillo Desalter would pump and treat brackish groundwater for potable water use and discharge reverse osmosis Final: 5/12/2011

64 2010 URBAN WATER MANAGEMENT PLAN Chapter 2 Water Supplies and Quality concentrate to the SMP. A Pilot Study Report prepared by CDM Consultants dated January 2009 indicates that up to 7,000 ac-ft per year of high quality potable water could be produced at this location on a sustainable basis. Water produced from this facility would be conveyed to nearby City of Camarillo distribution pipelines and also to nearby CMWD transmission pipelines for delivery to other CWMD purveyors. c. Moorpark Desalter Groundwater levels in the Moorpark region of the Calleguas Creek watershed have been rising for decades and it is estimated that a brackish groundwater recovery facility at this location could reliably produce up to 5,000 ac-ft per year of high quality potable water. Reverse osmosis concentrate from this proposed desalter would be discharged to the SMP and the potable water produced from this facility would be distributed by VCWWD No. 1. d. Other Potential Regional Desalters Other regional desalters are being considered and are in various stages of investigation, including desalters owned and operated by the agricultural community. Because these desalters are in the preliminary stages of investigation, potential local supplies produced from these facilities are not included in the local supply projections. However, as the projects become better defined, supplies from these facilities will be included. 4. Watershed Management Plans There are numerous on-going efforts to protect and improve the water quality within the Calleguas Creek watershed and enhance local water supplies. Information on water projects under consideration by the region, but not specifically discussed herein, can be found in the following two documents: Calleguas Creek Watershed Management Plan, 2004 Integrated Regional Water Management Plan for the Watershed Coalition of Ventura County, 2006 Projects presented in these two documents may yield new local supplies to CMWD purveyors. As these projects are further advanced, local supply projections within the CMWD service area will be updated appropriately Final: 5/12/2011

65 2010 URBAN WATER MANAGEMENT PLAN Chapter 3 Water Use and Demands Chapter 3 Water Use and Demands This chapter addresses water use characteristics and projected imported water demands on CMWD. Unless stated otherwise, demands are based on fiscal year (July 1 to June 30) projections. A. Past Water Use In 2005, the amount of water imported by CMWD from MWD was 116,432 ac-ft and the amount of local supplies utilized was 39,605 ac-ft. In total, 156,037 ac-ft of water was used in the CMWD service area in 2005, broken down by the following sectors: Single family 56.6 percent Multi-family 7.9 percent Non-residential 27.7 percent Unmetered and system losses 7.8 percent B. Water Use Figure 3-1 shows the distribution of average water deliveries by CMWD to its purveyors. As illustrated on Figure 3-1, CMWD s largest customer is the City of Simi Valley, which accounts for approximately one-fifth of the water distributed by CMWD. Water use by sector within CMWD s service area as estimated by MWD is listed in Table 3-1. MWD estimates system losses for CMWD s service area to be around 8 percent. CMWD records indicate losses within its distribution system of 0.34 percent and purveyor data indicate that combined system losses (CMWD and purveyor distribution systems) average 5 percent Final: 5/12/2011

(2) A detailed breakdown of water use by sector is provided in individual purveyor UWMPs. (3) Includes system losses in both CMWD s and its purveyor s systems. (4) CMWD records show the historical average is closer to 5 percent. Municipal and industrial uses are expected to account for approximately 90 percent of the water distributed by CMWD s purveyors through the planning period. Agricultural uses are expected to account for the remaining 10 percent. These proportions are forecasted to remain constant throughout the planning period. C. Demand Projections Similar to the supply projections, water demands for the CMWD service area were projected for three hydrologic scenarios: average year, dry year, and multiple dry years. It is worth noting that actual 2010 conditions did not fall into any of these categories as the weather in Ventura County was cooler than normal. As described below, both MWD and CMWD developed independent demand forecasts for the CMWD service area. MWD utilizes a top-down approach to demand projections based on output from the MWD-MAIN software model. CMWD demand projections are developed using a bottom-up approach based on demand projections developed by each CMWD member purveyor Final: 5/12/2011

70 2010 URBAN WATER MANAGEMENT PLAN Chapter 3 Water Use and Demands 1. Total Demand Projections MWD projections are shown in Table 3-2 and were developed using the MWD-MAIN Water Use Forecasting System. This model incorporates demographic and economic projections from regional planning agencies, and considers conservation and end uses.

CMWD is a member of the California Urban Water Conservation Council (CUWCC) and has been implementing water conservation BMPs since the early 1990s. These BMPs are discussed in more detail in Chapter 4. As expected, demands increase slightly during drier years. Comparing Tables 3-2 and 3-3, MWD s total demand projections for the CMWD service area are less than CMWD s projections. However, as discussed below, this is offset by the fact that MWD local supply projections for the CMWD service area are also less than CMWD s projections. 2. Imported Demand Projections Both MWD and CMWD estimated CMWD s imported water demand using the following formula: CMWD Imported Demand = Total CMWD Demands Local Supplies Imported water demands are calculated as the total demands for the CMWD service area less local supplies.

81 2010 URBAN WATER MANAGEMENT PLAN Chapter 4 Water Demand Management Chapter 4 Water Demand Management This section evaluates the current demand management measures that CMWD employs to reduce the demand for imported water. A. Demand Management Measures In the early 1990s, the CUWCC developed a Memorandum of Understanding (MOU) to provide guidance for implementing conservation measures as a way to manage water demands. CMWD is a member of the CUWCC and was a signatory of the MOU. The MOU originally included a list of 14 BMPs that define industry standards for implementing demand management measures. Most recently, these BMPs were organized into five categories: Utility Operations Foundational BMPs Utility Operations Education Programmatic BMPs Residential Commercial, Industrial and Institutional (CII) Landscape Table 4-1 lists the old BMP names and numbers along with the new BMP category Final: 5/12/2011

CMWD Conservation Programs CMWD has worked closely with its purveyors and MWD to implement BMP programs, even though many of the BMPs listed in Table 4-1 are not directly applicable to wholesale agencies. CMWD submits annual reports that summarize the status regarding implementation of BMP measures. Copies of the most recent annual reports submitted to the CUWCC are included in Appendix D and a description of each of CMWD s specific conservation programs is given below. 1. Water Loss Control (Formerly BMP-03) Every water agency has some degree of water loss, which can include system leaks, unmetered deliveries, or unmetered usage in locations such as water treatment plants. CMWD performs water audits and balances to monitor the amount of unaccounted water use. Average water loss in the CMWD distribution system is consistently less than 1 percent of the total water delivered Final: 5/12/2011

83 2010 URBAN WATER MANAGEMENT PLAN Chapter 4 Water Demand Management 2. Public Information Programs (Formerly BMP-07) CMWD promotes conservation, education, and public awareness programs through its website, tours, and speaking engagements. In 2008, CMWD increased the public awareness campaign in response to drought conditions. Advertisements were run in newspapers, movie theaters and on a billboard. In addition, as part of water rates paid to MWD, CMWD contributes to a Water Stewardship fund allowing MWD to continue such programs on behalf of their member agencies. Approximately $62,000 was spent on public information efforts in School Education Programs (Formerly BMP-08) CMWD has work closely within the state recommended framework to implement a school information program. These programs include free teacher inservice workshops, and tours and classroom presentations for grades kindergarten through 6. The primary focus of the various programs is to educate children on water resource issues including available water sources, water use and conservation. In 2008, CMWD allocated $6,000 for school education programs. 4. Wholesale Agency Assistance Programs (Formerly BMP-10) CMWD has worked closely with its purveyors and provided financial assistance in the implementation of several BMPs. CMWD sets aside $1 for every acre-foot of water sold, which has resulted in $100,000 to $120,000 per year of funds set aside to support implementation of BMPs. Any unspent monies roll over from year to year to support additional programs. Programs that typically receive such funds include: High efficiency washing machine rebates Public information programs School education programs Conservation coordinator programs Residential ULFT replacement assistance 5. Conservation Coordinator (Formerly BMP-12) CMWD has staff designated to the oversight and implementation of the conservation BMPs and the promotion of water conservation Final: 5/12/2011

84 2010 URBAN WATER MANAGEMENT PLAN Chapter 4 Water Demand Management C. Effectiveness of Conservation Measures The implementation of cost-effective BMPs provides mechanisms for both active conservation and financial incentives for reducing discretionary consumption. CMWD will continue to work with MWD and regional purveyors to identify new ways to control water consumption in a cost effective manner and will continue to measure and evaluate the effectiveness of the current conservation activities. Figure 4-1 presents historical water sales by CMWD and shows the effectiveness of the BMPs since they were implemented in the early 1990s. It is important to note that California experienced a severe extended drought from 1987 through Many water providers were forced to increase their water rates, which resulted in decreased water sales. This impact is illustrated on Figure 4-1 by the significant drop in water sales between 1990 and 1991 and certainly helped contribute to conservation, in addition to the implementation of BMPs. D. Water Reduction Target As discussed previously, SB 7 requires urban retail water supplies to reduce per capita water use 20 percent by Retail water providers can choose from four compliance methods, which are summarized as follows: Method 1. Determine baseline gallon per capita per day (gpcd) water use and reduce that amount by 20 percent. Baseline is defined as the average gross water use divided by the number of people in the service area, for a ten-year period ending no earlier than December 31, Gross water use is defined as the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier excluding recycled water and water used for agriculture. Method 2. Achieve all three of the following performance standards: residential indoor water use of no more than 55 gpcd, landscape water use commiserate with DWR s Model Water Efficient Landscape Ordinance, and a 10 percent reduction in baseline commercial, industrial, and institutional water use. Method 3. Achieve 95 percent of the DWR defined per capita water use target for the applicable hydrologic region. MWD and CMWD service areas are in the South Coast region, which has a baseline Final: 5/12/2011

87 2010 URBAN WATER MANAGEMENT PLAN Chapter 4 Water Demand Management target of 149 gpcd. Therefore, under this method, CMWD would have a 2020 target of 141 gpcd for its service area. Method 4. The fourth method is not yet adopted by DWR. Preliminary indications are that this method will include an aggregate of unique targets for residential, outdoor, and industrial type use. In November 2009, MWD prepared a paper titled Estimating the Water Savings Achieved with 20 percent by 2020 Compliance at the Member Agency Level. This preliminary assessment estimated a baseline per capita water use for the CMWD service area of roughly 209 gpcd, based on the 10-year period from 1995 to Using Method 1, the 20 percent reduction target would be approximately 167 gpcd. It is important to note that the purpose of the MWD analysis was to provide a high-level analysis. Compliance estimates were done at the Member Agency level, but the law will be applied at the retail service level. Therefore, actual targets for each CMWD purveyor could vary significantly from the value estimated for CMWD s entire service area. The reduced per capita target estimated by MWD was compared to CMWD s projected water supplies and uses for As shown in Table 4-2, a combination of additional recycled water projects or conservation beyond that included in the current projections will be required to meet the 2020 targets. CMWD and MWD intend to provide support for retail agencies efforts through technical assistance and continued financial assistance through the CMWD wholesale agency assistance program Final: 5/12/2011

89 2010 URBAN WATER MANAGEMENT PLAN Chapter 5 Reliability Planning Chapter 5 Reliability Planning This chapter evaluates the reliability of available supplies to meet demands and discusses MWD and CMWD strategies to maintain reliable water deliveries during single dry year and multiple dry year conditions. A. Supply versus Demand Evaluation This section evaluates MWD s and CMWD s reliability to meet demands during each of the hydrologic conditions. 1. Average Year Hydrologic Conditions As shown in Table 5-1, sufficient supplies are available to meet demands for average year conditions. On average, there is projected to be a water supply surplus of approximately eight percent annually through Table 5-1 CMWD Supply versus Demand for Average Year Conditions Parameter Volume (ac-ft per year) Average Year Demand 171, , , , , ,160 Average Year Local Supply 54,909 66,434 70,404 70,974 73,354 74,055 Imported Demand on MWD 116, , , , , ,105 MWD Available Supplies 118, , , , , ,777 Surplus/Deficit 1% 14% 16% 16% 14% 12% 2.

Actual allocation for 2010 was 112,042 ac-ft due to ongoing drought conditions and Bay-Delta issues. (2) Demand management measures and cooler than normal weather helped CMWD purveyors accommodate the reduced MWD allocation. For perspective, CMWD purveyors purchased 125,300 ac-ft of water from CMWD in 2008, 108,720 ac-ft in 2009, and 100,769 ac-ft in The reduction in 2009 and 2010 was due to implementation of both voluntary and mandatory restrictions imposed on the region due to ongoing drought conditions and reductions in available supplies from the Bay-Delta. Demand management measures and cooler than normal weather helped CMWD purveyors accommodate the reduced MWD allocation in Values presented in Table 5-2 for future years take into account the Bay- Delta Conservation Plan, which is anticipated to relieve several of the current Bay-Delta constraints. However, it is anticipated that restrictions will remain in place as long as the drought persists and as a result, a supply deficit of between 5 and 10 percent could occur in the near term.

Supply Reliability Strategies This section discusses water supply reliability strategies being implemented by DWR, MWD and CMWD. As a result of investments made in conservation, water recycling, transfer agreements, storage, and supply, MWD expects to be able to meet forecasted CMWD demands. Therefore, CMWD also expects to be able to meet the forecasted purveyor demands. 1. DWR Strategies Water for Southern California is pumped from the Bay-Delta into the SWP system. This pumping can create conflicts with natural flow patterns that stress the native habitat. In response to this stress, DWR has curtailed pumping from the Bay-Delta until some of these issues can be resolved. In addition to habitat concerns, the Bay-Delta relies on hundreds of miles of levees to separate seawater from the fresh water in the Bay-Delta. Levee assessments have shown that the levees are vulnerable to failure due to a seismic event Final: 5/12/2011

92 2010 URBAN WATER MANAGEMENT PLAN Chapter 5 Reliability Planning To address these and other related issues, DWR and the U.S. Bureau of Reclamation, in collaboration with California water agencies, environmental organizations, and the California Farm Bureau began work on the Bay-Delta Conservation Plan (BDCP) in The primary objective of the BDCP is to restore the Bay-Delta in a manner that results in both a more resilient ecosystem and more reliable water supplies. Alternatives for resolving the Bay-Delta issues have been identified and these alternatives are currently being evaluated as part of an environmental impact report (EIR) / environmental impact statement (EIS). As of December 2010, the Draft EIR/EIS is anticipated to be available for public review by mid The final decision (Record of Decision) on the alternative(s) to be used in the Bay-Delta is expected late 2012 to mid Once a record of decision has been issued, final permits must be secured before construction of the required facilities can proceed. Upon completion of these facilities, diversions from the Bay-Delta are anticipated to return to more historic and reliable levels. Additional information on Bay-Delta issues and the status of the BDCP can be found on the DWR website. 2. MWD Strategies MWD is implementing transfer agreements and storage strategies to increase the reliability of both SWP and Colorado River supplies. In addition to utilizing Diamond Valley Lake and shared portions of Lake Perris and Castaic Lake, MWD plans to develop off-stream storage facilities along the SWP California Aqueduct and the CRA. More detail on all of MWD s strategies for providing water supply reliability can be found in MWD s 2010 RUWMP. 3. CMWD Strategies CMWD operates several facilities that increase the reliability of the CMWD s supply to its purveyors. These facilities are discussed below. a. CMWD Stored Groundwater As shown on Figure 2-1, CMWD has stored a significant amount of water under FCGMA-approved storage programs in groundwater basins throughout the CMWD service area. This water can be extracted during times when imported supplies are curtailed Final: 5/12/2011

93 2010 URBAN WATER MANAGEMENT PLAN Chapter 5 Reliability Planning b. Lake Bard and Lake Bard Water Treatment Plant Lake Bard is located in the center of the CMWD service area and can store approximately 8,000 ac-ft of water. CMWD operates the Lake Bard WTP, which is adjacent to the lake and has a treatment capacity of 100 cfs. Supplies stored in Lake Bard can be used during times when imported supplies are curtailed. c. Salinity Management Project As described in Chapter 2, the SMP will facilitate treatment of local groundwater that is currently too saline for potable use. These desalters will improve overall regional supply reliability. d. Transfer Opportunities Water transfer agreements between agricultural and municipal water users are another method for increasing supply reliability. As a member agency to MWD, CMWD benefits from transfer agreements made through MWD. Therefore, CMWD does not currently pursue independent transfer agreements Final: 5/12/2011

95 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning Chapter 6 Contingency Planning CMWD has developed water shortage contingency plans in the event that MWD significantly reduces deliveries to its member agencies due to severe water shortage conditions or in the event that a catastrophe interrupts water deliveries. This chapter summarizes CMWD s water shortage contingency measures. A. Severe Drought Planning In 1999, MWD developed a Water Surplus and Drought Management Plan (WSDM Plan) that included guidelines for implementing water supply restrictions in the event of a water shortage. The WSDM Plan does not outline specific criteria for how water would be distributed among the MWD member agencies during water shortage conditions, but states that the methods to be used for determining reduction in supplies to each member agency would be developed in a manner that was equitable and minimized hardship to retail water customers. In 2007, MWD began to update their plans for addressing water shortage conditions. The impetus for this was a combination of on-going dry conditions and reduced deliveries from the SWP. In February 2008, the MWD Board adopted the Water Supply Allocation Plan. This plan is an extension of the WSDM Plan and includes specific formula for allocating available supplies among MWD member agencies. Table 6-1 summarizes the surplus and shortage actions to be taken by MWD as defined in the WSDM Plan. As shown, water shortage stage 7 is where the Water Supply Allocation Plan is implemented. In April 2009 and again in April 2010, MWD concluded that water shortage stage 7 conditions existed and the Water Supply Allocation Plan was implemented, resulting in reduced deliveries to all MWD member agencies Final: 5/12/2011

Call for extraordinary conservation / reduce Interim Agricultural Water Program (IAWP) deliveries. Call options contracts / buy spot water. Implement Water Supply Allocation Plan. 1. CMWD Water Shortage Stages of Action Table 6-2 presents water management actions that could be implemented by CMWD during both surplus and shortage conditions. CMWD s surplus and shortage stages of actions are intended to be consistent with the stages defined in MWD s WSDM Plan. It is important to note that the CMWD system is complex and the ultimate actions taken by CMWD will depend on the unique issues of each particular condition. In addition, CMWD s Ordinance No. 12 gives the Board of Directors authority to take actions necessary to manage available supplies, including passing through to member agencies allocations and penalties for exceeding allocated deliveries Final: 5/12/2011

97 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning Table 6-2 CMWD Water Shortage Stages of Action Guidelines Resource Stage Actions (1) Surplus Store water in groundwater basins throughout CMWD service area. Supply = Demand No actions required. (2) Stage 1 Shortage Call on purveyors to maximize local supplies, promote voluntary conservation. Stage 2 Shortage Begin withdrawals from CMWD stored groundwater. Stage 3 Shortage Call for extraordinary conservation efforts. Stage 4 Shortage Implement allocation program. (3) (1) Actions are additive as shortage conditions progress. (2) Deliveries will consist of purveyor demands and filling of Lake Bard. (3) CMWD will monitor consumption and asses penalties for excessive use. 2. Three-Year Minimum Supply Evaluation The UWMP Act requires that the minimum water supply be quantified based on the driest three-year historic sequence for each of the five year planning increments. The following tables evaluate the reliability of CMWD to meet demands assuming a linear increase between the two five year planning increments, linear increase in supply from MWD and no increase in local supplies. As shown on Tables 6-3 through 6-7, CMWD has developed water supply strategies to meet potential future multiple dry year events. Table 6-3 presents a three year minimum supply versus demand analysis for years 2010 through For comparative purposes, the 2010 average year supply and demand balance is also shown. An average shortfall of 10 percent is shown for 2011 through If this shortfall were to become a reality, CMWD could supplement with groundwater reserves and Lake Bard reserves, as well as implement short-term conservation measures Final: 5/12/2011

101 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning B. Catastrophe Planning Although MWD s and CMWD s water delivery systems are robust, these systems are still vulnerable. A natural event, such as an earthquake, could cause the complete and sudden failure of the facilities used by MWD to import water into the region. Similarly, the facilities used to import water from MWD to the CMWD service area are susceptible to these same threats. 1. MWD Catastrophe Plan The majority of Southern California s water is imported via three facilities, the California Aqueduct, Los Angeles Aqueduct, and the CRA. All three sources cross the San Andreas Fault. A catastrophic event that resulted in an unplanned interruption in supply from any of these facilities would have a significant impact on the ability to supply water. Consequently, MWD has invested heavily in emergency storage facilities located both in and out of the region. MWD anticipates that approximately 75 percent of average year demands could be delivered to its member agencies even if there was a disruption of service from one of these facilities. 2. CMWD Catastrophe Strategies CMWD is one of only a few MWD member agencies with only one connection for receiving imported supplies. In the event that service from this supply is disrupted, CMWD would be required to meet purveyor demands from water stored in Lake Bard and the local groundwater basins. Providing CMWD with a second water source was one of the primary reasons for development of the Las Posas groundwater basin. Lake Bard has a total storage capacity of 10,000 ac-ft; however, only 8,000 ac-ft are quantified as usable storage. The Lake Bard WTP extracts water stored in Lake Bard and can produce 100 cfs of potable water for a short period of time. Additionally, CMWD has accumulated on the order of 60,000 acre feet of groundwater storage credits under FCGMA-approved programs in basins within the CMWD service area. It should also be noted that CMWD can receive emergency supplies from the Los Angeles Department of Water and Power if there is a disruption in service from the MWD operated Jensen WTP. Utilizing a combination of Lake Bard and CMWD stored groundwater, CMWD can endure an extended disruption in service from MWD. Table Final: 5/12/2011

102 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning shows example strategies for meeting 2015 water demands during conditions of reduced deliveries from MWD.

(2) Defined as an interruption of 12 months. (3) Lake Bard facilities can supply 100 cfs for between 10 and 35 days, depending on initial lake levels. (4) Approximate amount of CMWD s accumulated groundwater storage credits under FCGMAapproved programs. (5) During an extended MWD outage, CMWD would request local purveyors to maximize local supplies 3. CMWD Emergency Pipeline Repair Protocol The CMWD distribution system has proven highly reliable for over 40 years. However, its potential vulnerability was demonstrated by the 1994 Northridge Earthquake, which resulted in numerous pipeline separations and cracked joints, and again in 1997 by an intense pressure surge that lead to the rupture of a 20 linear-foot section of a 66-inch diameter pre-stressed concrete pipe in Simi Valley. Recognizing the inherent vulnerability of water transmission systems, the CMWD Board of Directors adopted an Emergency Pipeline Repair Protocol in Final: 5/12/2011

103 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning The intent of this protocol is to establish a state of preparedness and an organized, planned procedure to mobilize and begin work. The plan facilitates timely emergency response and assures that repairs will be performed in the most efficient manner. Large diameter pipeline failures, if not addressed promptly and properly, can inconvenience thousands of customers and cause considerable property damage. Facility failures may be caused by construction activity, earthquakes, power failures, or other conditions such as pressure surges (i.e., water hammer). While failures can be expected, their locations are unknown until they occur, which dictates that a repair protocol be applicable to a broad range of situations and locations. Furthermore, the more quickly the failure can be repaired, the less likely it will cause debilitating damage or service outages. In preparing the protocol, CMWD identified factors that could enhance the efficiency with which emergency repairs are performed, and developed specific actions to improve emergency repair procedures. In an effort to learn from the experiences of others in the water industry, meetings and discussions were held with pipeline suppliers and other vendors as well as with other large water providers including MWD and the San Diego County Water Authority. The findings indicated that the key to efficient repair procedures is a structured approach, in which specific procedures, responsible personnel and necessary equipment are identified and secured ahead of time. With this in mind, CMWD developed a protocol that includes a step-by-step procedure for responding to an emergency. The key elements of the protocol are: Establishment of an emergency repair organizational structure. Redevelopment of a spare pipe and fittings inventory and management of inventory records. Identification of emergency contacts. Damage assessment. Comprehensive repair drawings, specifications, and procedures for various facility types. Ongoing maintenance of the protocol Final: 5/12/2011

104 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning Rapid mobilization of repair crews is dependent upon having equipment and replacement pipe and appurtenances at the ready. CMWD s plan contains recommendations for the stockpiling of a total of seven sizes of replacement pipe, in diameters ranging from 24 to 78 inches. This pipe has been purchased and is stored at CMWD s Lake Bard and well field properties. Having this inventory available gives CMWD the ability to quickly repair up to 98 percent of the pipelines in its distribution system in a timely manner. C. Water Quality Contingency Planning Changes in drinking water regulations, environmental litigation, or identification of a new contaminant could result in the loss of an existing water supply source. This section discusses how water quality concerns could impact the reliability of the regional water systems. 1. MWD Water Quality Contingency Planning To reduce the potential impact from a decrease in water supply due to water quality, MWD has instituted a 10 percent planning buffer requirement. This buffer requires the identification of contingency supplies equal to 10 percent above that needed to meet 2025 demands. These supplies allow for a more speedy response and are to be used only if existing supplies become unavailable. 2. CMWD Water Quality Contingency Planning CMWD manages two major local storage facilities, Lake Bard and the Las Posas ASR Facilities. Lake Bard is relatively small and is primarily intended to provide operational flexibility to CMWD rather than to serve as a consistent water supply. Contamination of the lake is an unlikely event as the lake and its watershed are owned by CMWD and access is restricted. However, if the lake was deemed unusable due to water quality, only approximately 5 percent of CMWD s total annual demands would be affected. It is anticipated that this lost supply could be supplemented with additional imported water from MWD or by extracting water from CMWD stored groundwater. Stored groundwater is also an important part of CMWD s water resource mix and potential water quality related issues with groundwater would have an impact on the ability to meet demands Final: 5/12/2011

105 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning If a water quality issue occurred in the Las Posas or other local basins, it would likely be resolved with treatment upon extraction. In the event that the existing treatment facilities were not capable of removing the contaminant, CMWD would rely on MWD to deliver additional imported water until the facilities could be upgraded to remove the contaminant. D. Provisions to Reduce Water Consumption Under the most severe drought conditions and under almost any catastrophe condition, CMWD may call for mandatory reduction in water consumption. This section presents guidelines to reduce water consumption and identifies measures that could be utilized by CMWD to monitor and enforce reduced water consumption. 1. Guidelines for Meeting Reduced Consumption Mandates In the event that a mandatory reduction in water consumption is required, one or all the following guidelines can be implemented to meet the water consumption goals: Disallow non-essential irrigation and limit water use for essential irrigation. Restrict irrigation to evening and early morning hours. Restrict or disallow the use of sprinklers during all hours. Limit or disallow the use of potable water for golf course and park irrigation. Disallow the use of water to fill ornamental lakes, ponds, pools, and fountains. Limit or disallow the washing of vehicles. Disallow the spraying of outdoor paved surfaces and using potable water for street cleaning. Request that restaurants not serve water to customers unless specifically requested. Restrict the use of water from fire hydrants for construction purposes Final: 5/12/2011

106 2010 URBAN WATER MANAGEMENT PLAN Chapter 6 Contingency Planning Develop a rate structure for charges and penalties for water use restriction violations. 2. Monitoring and Enforcing Reduced Consumption Mandates California Water Code Section f allows urban water suppliers to charge penalties for excessive water use in order to encourage consumption reduction during a water shortage. Under the current Water Shortage Allocation Plan adopted by MWD, any time a member agency takes 102 percent of their reduced allotment under a declared Stage 7 shortage condition, they will be assessed a surcharge equal to three times the MWD full service rate. To meet MWD reduced allotments during water shortages, CMWD may be required to reduce allotments in-kind. CMWD can monitor daily water consumption and issue penalties for excessive use during declared shortage conditions using existing water metering facilities. Additionally, CMWD is currently in the design phase of the Turnout Automation Project. When complete, the system will provide monitoring of flow conditions at all turnouts and will provide real time flow data to both CMWD and its purveyors. The Turnout Automation Project will assist in more efficient operations during both water shortage conditions and normal operating conditions. 3. Fiscal Impacts from Reduced Water Deliveries During periods of reduced consumption, revenue from water sales will decline while expenses remain relatively constant. A natural disaster may also entail unpredicted expenditures for repairs. Therefore, it is imperative that CMWD have adequate reserves to cover operating and emergency repair expenses during these periods. Historically CMWD has budgeted conservatively and in so doing, it has built up substantial reserves. CMWD can operate several months without revenue from water sales while at the same time paying for significant repairs to its system due to an unexpected event. If periods of reduced consumption are prolonged, CMWD may be required to adjust rates to remain financially stable Final: 5/12/2011

Each operator of a registered extraction facility shall enter the necessary information and return the Semi- Annual Groundwater Extraction Statement covering all wells they operate on or before the due date. Statements are due on or before February 1st or August 1st annually or thirty days after the date of the letter requesting submittal of the Semi-Annual Statement 5

130 for the given period. Statements shall contain the following information on forms provided by the Agency: The information required under Section above The method of measuring or computing groundwater extractions The crop types or other uses and the acreage served by the extraction facility Total extractions from each extraction facility in acre-feet for the proceeding six (6) month period Groundwater Extraction Charges All persons operating groundwater extraction facilities shall pay a groundwater extraction charge for all groundwater extracted after July 1, 1993, in the amount as established by Resolution. Payments are due semi-annually, and shall accompany the statement required pursuant to Section Payments are due forty-five (45) days after the billing date, and payments not received or postmarked by such date due shall be charged interest from and after such date due until payment thereof at the rate of 1.5 percent per month, or part of month that the charge remains unpaid. Late Penalty. The operator shall pay a late penalty for any extraction charge not satisfied by the due and payable date. The late penalty shall be 1½ percent per month, or any portion thereof, of the amount of the unsatisfied extraction charge. The late penalty shall not exceed 100% of the original charge, provided the penalty is paid within 60 days of the due date. If the fee is not paid within the 60 days, the penalty will continue to accrue at 1.5 percent per month with a final maximum of 200% of the original penalty due Owners of extraction facilities are ultimately responsible for payment of pumping charges and penalties should an operator not pay. Consequently, owners are charged with providing for this liability in agreements entered into with well operators and water users Collection of Delinquent Extraction Charges and Late Penalties - The Board may order that any given extraction charge and/or late penalty shall be a personal obligation of the operator or shall be an assessment against the property on which the extraction facility is located. Such assessment constitutes a lien upon the property, which lien attaches upon recordation in the office of the County Recorder. The assessment may be collected at the same time and in the same manner as ordinary ad valorem taxes are collected, and shall be subject to the same penalties and the same procedure and sale, in case of delinquency as provided for such taxes. All laws applicable to the levy, collection and enforcement of ad valorem taxes shall be applicable to such assessment, except that if any real property to which such lien would attach has been transferred or conveyed to a bona fide purchaser for value, or if a lien of a bona fide encumbrance for value has been created and attaches thereon, prior to the date on which the first installment of such taxes would become delinquent, then the lien which would otherwise 6

131 be imposed by this section shall not attach to such real property and an assessment relating to such property shall be transferred to the unsecured roll for collection Use of Extraction Charges and Late Penalties - Revenues generated from extraction charges and late penalties shall be used exclusively for authorized Agency purposes, including financial assistance to support Board approved water supply, conservation, monitoring programs and water reclamation projects that demonstrate significant reductions in overdraft. CHAPTER 3.0 Installation and Use of Flowmeters for Groundwater Extraction Facilities 3.1. Installation and Use of Flowmeters Installation Requirement - Prior to extracting groundwater, the operator shall install a flowmeter. With the exception of connections used for well flushing and extraction facilities used by multiple operators, flowmeters shall be installed upstream of all connections to the main discharge line. Flowmetering is not required during well flushing and well rehabilitation; however, the volume of water extracted shall be estimated and reported to the Agency. Flowmeters are not required on inactive wells as defined in this Ordinance Code, nor are flowmeters required for extraction facilities supplying a single family dwelling on one acre or less, with no income producing operations. If more than one operator uses the same extraction facility, flowmeters shall be installed to record the water use of each operator. Well operators were required to install flowmeters on wells by July 1, Flowmeter Failure and Back-up Measurement Requirements - Flowmeters occasionally fail, losing periods of record before the disabled or inaccurate meter is either replaced or repaired. When a flowmeter fails, the operator shall repair or replace the flowmeter within the timeframe specified in a separate Resolution. Flowmeter failures and associated repairs or replacements shall be reported to the Agency together with any other information required by the Executive Officer on or before the due date of the next Semi-Annual Groundwater Extraction Statement. Well operators shall be prepared to provide another acceptable method of computing extractions during these periods of flowmeter failure to avoid the loss of record on wells that require flowmetering under this Ordinance Code Back-up Methods - It is the operator's responsibility to maintain the flowmeter. Any allowable or acceptable backup measurement methods will be specified in a separate Resolution and may be changed as technology improves or changes Flowmeter Readings - Functional flowmeters shall be read and the readings reported semi-annually on the extraction statements required under Section 2.3 above. 7

132 Inspection of Flowmeters - The Agency may inspect flowmeter installations for compliance with this Ordinance Code at any reasonable time Flowmeter Testing and Calibration - All flowmeters shall be tested for accuracy at a frequency interval determined by the Board to meet specific measurement standards. Calibration methods and procedures approved by the Board shall be detailed in an adopted Resolution Altering Flowmeters - Any person who alters, removes, resets, adjusts, manipulates, obstructs, or in any manner interferes or tampers with any flowmeter affixed to any groundwater extraction facility required by this Ordinance Code, resulting in said flowmeter to improperly or inaccurately measure and record groundwater extractions, is guilty of an intentional violation of this Ordinance Code and will be subject to any and all penalties as described in Chapter Costs of Testing and Calibration - All costs incurred with flowmeter testing or calibration shall be the personal obligation of the well owner. Non-compliance with any provision of the flowmeter calibration requirements will subject the owner to financial penalties and/or liens as described below or in Chapter 8 of the Ordinance Code Fees and Enforcement - If any water production facility within the Agency's boundaries is used to produce water without a flowmeter or with a non-operating flowmeter in excess of the allowable timeframe specified in a separate Resolution, the Agency shall assess a Non-Metered Water Use Fee against the water production facility owner. The amount of the fee shall be calculated as follows: Groundwater extraction facilities - The fee shall be equal to double the current groundwater extraction charge for all estimated water used. Estimates of water used shall be calculated by the operator and approved by the Executive Officer. Any delinquent extraction charge obligations shall also be charged interest at the rate of 1.5 percent per month on any unpaid balances Upon violation of any flowmeter provision, the Agency may, as allowed by law, petition the Superior Court of the County for a temporary restraining order or preliminary or permanent injunction prohibiting the well owner from operating the facility or for such other injunctive relief as may be appropriate. CHAPTER 4.0 Protection of the Las Posas Basins 4.1. This chapter has the following purpose and intent: To eliminate overdraft from the aquifer systems within the boundary of the East and West Las Posas basins and bring these basins to a safe yield condition by the year

133 To protect the Las Posas outcrop as a source of groundwater recharge into the East and West Las Posas basins To prevent groundwater quality degradation of the East and West Las Posas basins by influence from the Expansion area This Ordinance Code is only one means by which these goals will be met Anti-degradation and Extraction Prohibition Extraction Facility Permits Permit Required - Prior to: (a) initiating any new or increased use of groundwater in the Expansion area, obtained from any source within the Agency including the Expansion area; or (b) constructing a new or replacement extraction facility in the East or West Las Posas basins, or the Expansion area, a permit must be obtained from the Agency as provided in this Chapter. For the purpose of this Chapter, a new or increased use is that which did not exist or occur before June 30, Permit Application - Application shall be made to the Agency on the approved County Water Well Ordinance form available from the County Public Works Agency and shall include all information required by the County Well Ordinance and the following: Location of each water well to be used, along with the associated state well number Location(s) of groundwater use, including acreage accurately plotted on copy of the County Assessor s Parcel Map The proposed crop type(s) or Municipal and Industrial use(s) at each location A brief description of the type of irrigation or distribution system and flowmeter to be used The estimated average annual quantity of water use proposed for each location of use An identification of the source of historical allocation to supply the proposed water use by the well An analysis of the potential impacts on the water balance in the Las Posas Basins resulting from the proposed use(s) Findings - A permit may only be granted if the Executive Officer finds that the proposed groundwater use will result in no net detriment to the East or West Las Posas Basins by determining that: 9

134 The Las Posas outcrop is not exposed to potential degradation of water quality of any type, and Recharge to the East and West Las Posas Basins from the Las Posas outcrop is not diminished, and Neither baseline nor efficiency allocation will be used, directly or indirectly, to support groundwater use on the Expansion Area, and (an example of indirect use is using efficiency to supply a demand inside the Agency and using the replaced historical allocation on the outcrop) No increased or new uses of groundwater from inside the Agency Boundary will be applied on any area outside the Expansion area (or outside the East or West Las Posas boundary) Permit Conditions. The Executive Officer may include in the permit granted, any conditions consistent with the purpose of this Chapter, including: Any proposed agricultural use shall include the installation of irrigation systems that employ irrigation best management practices consistent with then current industry standards Any proposed municipal or industrial use shall include the installation of systems that employ municipal and industrial best management practices consistent with the then current industry standards A permit term, not to exceed 10 years from the date of issuance Mitigation, monitoring, and periodic reporting, as may be appropriate given the proposed use Permit Renewal - Permits may be renewed pursuant to the requirements of Section Registration of Existing Uses - The owners of groundwater wells located within the East or West Las Posas basins shall register their wells with the Agency no later than January 1, 2006, through the following procedure: Registration Form - The Agency shall make available a registration form which shall be completed, and filed with the Agency for each well, which shall include the following: 10

135 Location(s) of all water well(s), along with the associated state well number(s) including offsite well(s) serving the proposed use. Information concerning wells shall also include any other use for the water well Location(s) of groundwater use for the well including acreage accurately plotted on a copy of the County Assessor s Parcel Map The proposed crop type(s) or Municipal and Industrial use(s) at each location A brief description of the type of irrigation or distribution system and flowmeter in use The estimated average annual quantity of water use at each location and for each well Monitoring - The Agency shall monitor compliance with this Chapter by reviewing County well permit applications and reported groundwater extractions and by conducting field surveys as may be necessary. 4.5 Unreasonable Uses - The Agency may commence and prosecute legal actions to enjoin unreasonable uses or methods of use of water within or without the Agency Boundary to the extent those uses or methods of use adversely affect the groundwater supply within the Agency Boundary. CHAPTER 5.0 Reduction of Groundwater Extractions 5.1. Purpose - The purpose of this Chapter is to eliminate overdraft from the aquifer systems within the boundaries of the Agency and bring the groundwater basins to safe yield by the year It is not the purpose of this Chapter to determine or allocate water right entitlements, including those, which may be asserted pursuant to California Water Code sections , or Extraction Allocations General Limitations The Executive Officer shall establish an operator's extraction allocation for each extraction facility located within the Agency Boundary. The extraction allocation shall be the historical extraction as reported to the United Water Conservation District and/or to the Agency pursuant to Chapter 2 (or its successor), reduced as provided by Section 5.4, or as otherwise provided for in Section 5.6 of this Ordinance Code. An alternative allocation, either baseline or efficiency, may also be approved as explained in Sections and All extraction facilities have an allocation of zero unless the Executive Officer 11

136 determines otherwise. The operator may determine whether the annual allocation used shall be either a combination of baseline and historical allocation, or based on an efficiency allocation. All wells used by an operator in any given basin shall be operated on either a combination of historical and baseline or an efficiency allocation except water purveyors as approved by the Executive Officer. As explained by Section , an efficiency allocation may not be combined with either a baseline or a historical allocation. Extraction allocations may be adjusted or transferred only as provided in Section Regardless of allocation, the total water use for agricultural purposes must be at least 60 percent efficient as determined by the formula described in Section This 60 percent irrigation efficiency is totally unrelated to the 80 percent efficiency described in Section , Annual Efficiency Extraction Allocation Where an operator operates more than one extraction facility in the same basin, the extraction allocations for the individual facilities may be combined Where there is more than one operator for any agricultural extraction facility, each operator shall be entitled to a pro rata share of the facility's historical allocation based on either usage or acreage irrigated during the historical extraction period. Such pro rata shares shall be determined by the owner of the extraction facility, and this determination shall be subject to the approval of the Executive Officer When an operator is no longer entitled to use an extraction facility, that operator is no longer entitled to any portion of the extraction allocation attributed to that extraction facility A historical allocation is assigned to an extraction facility and a baseline allocation is assigned to the land, both may be used, but neither is owned by the operator Where there is a sale or transfer of a part of the acreage served by any extraction facility, the extraction allocation for that facility shall be equitably apportioned between the real property retained and the real property transferred by the owner of the extraction facility, This apportionment shall be approved by the Executive Officer who may modify the apportionment to assure equity The name of the owner of each extraction facility, the parcel number on which the well is located along with the names of all operators for each extraction facility shall be reported to the Agency with each semi-annual statement and within 30 days of any change of ownership or operators, together with such other information required by the Executive Officer. 12

137 The Executive Officer may, on written request from a land owner or well operator, waive allocation requirements for the extraction of groundwater from the Perched or Semi-perched aquifer of Sealing Zone III when the pumping of that groundwater is specifically for the purpose of lowering the water table to reduce the high water table threat to property, including the root zone of crops, or for dewatering construction sites. The Executive Officer shall require that the groundwater extraction facility used for this purpose be perforated only in the Perched or Semi-perched zone, and shall also require the landowner and/or the operator to protect the Agency from damage potentially caused by transferring water to another location General Limitations: Special Board Approval Requirements - Notwithstanding any other provisions of this Ordinance Code, the following uses of water resources associated with the aquifers within the Agency may only be undertaken with prior Board approval of and subject to the conditions and restrictions established by the Board Direct or indirect export of groundwater extracted from within the Agency Boundary for use outside the Agency Boundary The direct or indirect use of surface water or Foreign Water from within the Agency outside the Agency in a manner that may adversely affect the groundwater supply within the Agency Application to the Board - To obtain the approval of the Board for any use provided in Sections and , application shall be made to the Agency describing the details of the proposed use, including all the following information: The location of each water well to be used, along with the associated state well number, and/or the location of each surface diversion and a description of the associated water right Location(s) of groundwater use, including acreage, accurately plotted on copy of the County Assessor s Parcel Map The proposed crop type(s) or Municipal and Industrial use(s) at each location A brief description of the type of irrigation or distribution system and flowmeter to be used The estimated average annual quantity of water use proposed for each location of use An identification of the source of historical allocation, if any, to supply the proposed water use by the well. 13

138 An analysis of the potential impacts on the water balance in any Basin or Subbasin within the Agency Boundaries resulting from the proposed use(s) Findings - The Board may approve the proposed use if, after a public hearing, it finds that the proposed use will result in no net detriment to the Basin, or any subbasin, or aquifer associated with the use, by determining that: The proposed use does not result in the material degradation of water quality of any type, or Recharge to any aquifer within the Agency is not materially diminished In granting approval to projects subject to this subsection, the Board may impose any conditions as may be appropriate, including limitations on the quantity of water use, term of the approval, and periodic reporting to the Agency An operator shall comply with all provisions of this Ordinance Code and Resolutions prior to receiving an extraction allocation Adjustments to Extraction Allocations Adjustments to extraction allocations may be necessary to provide some flexibility, while still maintaining the goal of reaching a safe yield condition by the year Adjustments may be accomplished by a transfer, an assignment of historical extraction allocation, or a demonstration of a new water source Subject to the provisions in this Section 5.3, transfers of extraction allocation are authorized provided they result in no net detriment to the Basins within the Agency. In making this determination, consideration shall be given to the location of extraction facilities, the aquifer systems being used, potential groundwater quality impacts, and the overall assessment of the cumulative impacts of transfers of extraction allocation Types of Transfers of Allocation. When irrigated agricultural land(s) changes to M & I use, a basic extraction allocation of 2 acre-feet per acre shall be transferred. In addition, a historical extraction allocation shall be transferred from the agricultural extraction facility(s) operators to the M & I provider in accordance with the following conditions: When the extraction facility is located on the land transitioning and did not serve other land during the historical allocation determination period, the M & I Operator shall receive a historical extraction allocation of 2 acre-feet per acre per year for the acreage transitioning to M & I use. Any historical allocation in excess of 2 acre-feet per acre for the land transitioning to M & I use shall be eliminated. 14

139 When the extraction facility is located on the land transitioning and served other land during the historical allocation determination period, the historical allocation associated with the transitioning property shall be allocated on a pro rata basis by acreage to the total property served. The pro rata share for the property transitioning shall be eliminated. Two acre-feet per acre per year, based upon the acreage being transferred, shall be provided to the M & I provider When the extraction facility serving the lands transitioning is not located on the land transitioning, the Executive Officer shall determine the allocation on an equitable basis for the remaining properties not transitioning to M & I. Two acre-feet per acre per year, based upon the acreage being transferred, shall be provided to the M & I provider The transfer shall be effective upon the approval of the Executive Officer, taking into account the ongoing use of the property Allocation originating from an agricultural extraction facility shall not be transferred to an M & I use except as provided in this Section Allocation may be transferred between M & I extraction facilities provided there is no net detriment to the aquifer system. In making this determination, the Executive Officer shall, at a minimum, consider the location of extraction facilities, the aquifer system being used and groundwater quality impacts of the transfer Transfer of Allocation - Upon request, the Executive Officer may transfer allocation from one agricultural operator to another agricultural operator or from one M & I operator to another M & I operator provided there is no net detriment to the basins and the transfer is equitable. The transfer of allocation will be of indefinite duration, approved on a "case-by-case" basis, and the Executive Officer shall determine the rate of extraction and the point or points of extraction. Requests for the transfer of allocations shall be submitted jointly by the parties involved and shall include the specific details of their proposal. To ensure that there is no net detriment to the aquifer systems, transfers of allocation shall be subject to other conditions as approved by the Board. Transfers of allocation from Agricultural use to M & I use shall only be approved as provided by Section The Executive Officer may approve a temporary assignment of allocation from one operator to another operator when there is no net detriment to the aquifer system. The temporary assignment shall not exceed one year Adjustments to M & I Allocations - The Board may adjust the historical allocation of an M & I operator when that operator has supplied groundwater to either an agricultural or M & I user during the historical allocation period and discontinues service to that user. This adjustment may be made by transferring the supplied portion of the historical allocation from the M & I operator to the new user. This adjustment will avoid increased pumping due to windfall allocations that could 15

140 otherwise result when the M & I operator discontinues service. To avoid retroactive inequities, where an M & I operator has discontinued service to a user prior to July 1, 2005, the amount of the supplied portion of the historical allocation may be allocated to both the M & I operator and the user Historical allocation is subject to adjustment as provided in Section 5.4 below Procedures for Adjustment It shall be necessary for the operator of the extraction facility to file a verified Application for Adjustment with the Executive Officer Adjustments of extraction allocations, pursuant to the Applications for Adjustment, shall be considered for approval by the Board after reviewing the findings and recommendations of the Executive Officer and, if approved, shall be effective for the remainder of the calendar year and for all subsequent calendar years until modified by a subsequent Board approved adjustment Reduction of Extraction Allocations Historical extraction allocations, adjusted or otherwise, shall be reduced in order to eliminate overdraft from the aquifer systems within the boundaries of the Agency for agricultural and M & I uses. The reductions shall be as set forth below: extraction allocation = 95% of historical extraction, as adjusted extraction allocation = 90% of historical extraction, as adjusted extraction allocation = 85% of historical extraction, as adjusted extraction allocation = 80% of historical extraction, as adjusted. After 2009 extraction allocation = 75% of historical extraction, as adjusted Following the appropriate public review, the Board may exempt historical extraction allocations from these adjustments on a basin-by-basin basis Exemptions from Reductions The following types of extraction allocations are exempt from the reductions set forth in Section 5.4.1: Baseline Extraction Allocations as set forth in Annual Efficiency Extraction Allocations as set forth in Non-metered Extraction Facilities. Reductions in extraction allocations shall not apply to those extraction facilities as identified in Chapter 3 that do not require flowmeters. Neither retroactive adjustments nor refunds will be made, except that any outstanding surcharges for non-metered extractions that existed prior to June 26, 2002 will be waived. 16

141 5.6. Alternative Extraction Allocations As an alternative to historical extractions, the Executive Officer may establish a Baseline or an Annual Efficiency extraction allocation for an operator, as follows: Baseline Extraction Allocations. If no historical extraction exists, or the historical allocation is less than one acre-foot per acre per year, a Baseline extraction allocation may be established by the Executive Officer at one acre-foot per acre per year A Baseline Extraction Allocation specifically applies to undeveloped acreage that is being developed and once approved shall remain with that developed acreage. A Baseline allocation may be combined with a historical allocation for commonly operated facilities in the same basin. A baseline allocation shall not be used with an efficiency allocation To obtain a Baseline Extraction Allocation, a detailed report must be submitted to the Executive Officer. The report shall describe the historical extraction of groundwater use, if any, during the period between the end of calendar year 1984 and the end of calendar year 1989, the type (crop type or M & I) and the amount of water use and acreage involved. The report shall include copies of Assessor's maps identifying the parcels where groundwater is presently being used. For the purpose of this ordinance, one (1) acre-foot per acre per year represents a reasonable use of water for a Baseline extraction allocation Application for the initial Baseline Extraction Allocation must be submitted prior to submission of the annual report of pumping. If approved, the Baseline Extraction Allocation shall apply beginning with the current calendar year To facilitate accounting procedures, an operator shall use Baseline Extraction Allocation before using Historical Allocation Annual Efficiency Extraction Allocation - If an operator can demonstrate to the Executive Officer that water used for agriculturally developed land is at least 80 percent overall irrigation efficient, based on evapotranspiration requirements, an Annual Efficiency extraction allocation shall be established for one calendar year. An 80 percent overall irrigation efficiency has been determined by the Agency to be reasonable on agricultural lands within the Agency's boundaries An Efficiency Allocation may be used when no historical allocation exists or when the historical allocation is not 17

142 sufficient for the crop being grown. A historical allocation shall not be used in conjunction with an efficiency allocation To prove that irrigation efficiency is at least 80 percent, the operator must submit a detailed report covering a minimum period of the immediately preceding calendar year. This report shall be submitted to the Executive Officer no later than February 1st of the following year unless otherwise extended by the Board. The report shall include a complete crop and irrigation history for the extraction facility and actual acreage irrigated. The report shall include the reference evapotranspiration (ETo) rates and crop factors (Kc) for the calendar year period similar to that provided by the California Irrigation Management Information System (CIMIS) as developed and modified by the California Department of Water Resources. The report shall include a summary sheet that compares the water use to the evapotranspiration requirements for each crop and the corresponding acreage covered in the calendar year. The Board may extend the time to apply for an efficiency allocation for any year Irrigation efficiency will include an appropriate amount of water necessary to avoid salt build-up based on the quality of irrigation water used Irrigation Efficiency (I.E.) will be calculated using the following formula: Where: I.E. = [ETo x Kc] - ER x 100 Actual Water Applied (inches) ETo is the reference evapotranspiration measured in inches. Kc is a crop factor, which is a dimensionless number that relates water use by a given plant in comparison to ETo. ER is the effective rainfall measured in inches as determined by the Executive Officer Exceptions - The Board may grant exceptions to Sections and on a case-by-case basis. However, individual exceptions shall not become the norm. Where agricultural efficiency cannot be measured as set forth in Section , then the most efficient practices of record for the type of agricultural use shall be the measurement of efficiency utilized by the Board in its deliberations. 18

143 5.7. Credits Credits can be obtained by operators, but are not considered as extraction allocations or adjustments to extraction allocations. Credits are not subject to any reductions as set forth in Section Credits, if available, shall be used to avoid paying extraction surcharges. Credits shall be accounted for through the normal reporting and accounting procedure and are carried forward from year to year. Except as provided below, credits may be transferred between commonly operated extraction facilities and within the basin where the credits were earned The Board may transfer credits between facilities that are not commonly operated within a basin or beyond the basin where such credits were earned, provided that there is no net detriment to the aquifers within the Agency. In determining whether there is no net detriment, the Board may, among other things, consider whether the transfer will help bring the aquifers within the Agency into equilibrium or whether the transfer is a part of an Agency or inter-agency management plan or program to bring the aquifers of the Agency into balance. Also, in making this determination of no net detriment the Board may consider quality of water as well as the quantity. The transfer of credits will be of indefinite duration, approved on a "case-by-case" basis, and the Executive Officer shall determine the rate of extraction and the point or points of extraction Requests for the transfer of credits shall be submitted jointly by the parties involved and shall include the specific details of their proposal. To ensure that there is no net detriment to the aquifer systems, transfers of credits shall be subject to other conditions as approved by the Board. Under no circumstances shall credits earned as a result of agricultural use be transferred to an M & I Provider, M & I Operator or an M & I User unless the transfer is specifically approved by the Board and no net detriment to the aquifer systems involved can be shown. Credits earned by an M & I facility shall remain with that facility unless transferred by the Board or transferred as part of a program such as an Agency or inter-agency management plan or program approved by the Board. The types of credits are: Conservation credits - An operator can obtain conservation credits by extracting less groundwater than the historical extraction allocation. Annual Efficiency, Baseline, or an allocation assigned to an extraction facility that is not required to have a flowmeter shall not earn credits. Credits shall be determined by the Executive Officer after receipt of annual extraction data. Subsequent to determining the amount of credits earned, a confirmation shall be mailed to the operator indicating the current allocation, the groundwater extracted during the previous calendar year, and the credits or surcharges for the previous year Storage credits - An operator may obtain storage credits for water that has been determined by the Board to qualify for 19

144 credits or foreign water stored, injected or spread and percolated or delivered in lieu of pumping in a Board approved injection/storage program used within the Agency Boundary. A written application for approval of a program or an injection/storage facility shall include: Operator of proposed injection/storage program Purpose of proposed injection/storage program Location, depth, casing diameter, perforated interval and other information regarding proposed injection/extraction facilities, if applicable Method of operation including source, quantity and quality of water, planned scheduling of storage, injection/extraction, delivery or percolation operations and proposed use of extracted water Any other information deemed necessary by the Executive Officer Following Board approval of the application, successful storage, delivery or injection of water and reporting of results, an operator will obtain credit as determined by the Executive Officer Extraction Surcharges and Late Penalty Necessity for Surcharges Extraction surcharges are necessary to achieve safe yield from the groundwater basins within the Agency and shall be assessed annually when annual extractions exceed the historical and/or baseline allocation for a given extraction facility or the combined sum of historical allocation and baseline allocation for combined facilities. The extraction surcharge shall be fixed by the Board and shall be based upon (1) the cost to import potable water from the Metropolitan Water District of Southern California, or other equivalent water sources that can or do provide nonnative water within the Agency jurisdiction; and (2) the current groundwater conditions within the Agency jurisdiction At the discretion of the Board, the extraction surcharge may be structured, tiered, and varied between basins and or aquifers The Board shall fix the surcharge by Resolution at a cost sufficiently high to discourage extraction of groundwater in excess of the approved allocation when that extraction will adversely affect achieving safe yield of any basin within the 20

145 Agency and may adjust the surcharge by Resolution; provided however, that the then existing extraction surcharge shall remain in effect until adjusted by the Board Surcharge for No Allocation - In circumstances where an individual or entity extracts groundwater from a facility(s) having no valid extraction allocation, the extraction surcharge shall be applied to the entire quantity of water extracted. Imposition and acceptance of payment of the surcharge imposed on an individual or entity that extracts water from a facility(s) that holds no extraction allocation shall not be deemed a waiver of the Agency s authority to limit or enjoin the unauthorized extractions Efficiency Surcharge Facilities relying on the annual efficiency allocation shall also be subject to surcharge for inefficient use. The extraction allocation for efficiency is the amount of water used at 80% efficiency as defined in of this ordinance. Extraction surcharges will be applied to the difference between the water extracted which correlates with the actual efficiency achieved and the water that would have been extracted to attain the 80% efficiency allocation. For example, an actual efficiency of 70% would be subject to surcharges on the difference between the amount of water used at 70% efficiency and the amount of water that would have been used at 80% efficiency. If an efficiency of less than 60% is achieved, no efficiency allocation will be available, and the operator shall revert to a historical, baseline or to no allocation whichever applies to that facility. Extraction surcharges would then apply to the difference between actual water used and the applicable allocation, if any. For example, a facility operating at an actual efficiency of 59% with no historical or baseline allocation, would be subject to surcharges on all water used Payment of Extraction Surcharges Surcharges are assessed annually with respect to the annual allocation and shall become due and payable by the owner/operator on February 1 st each year or 30 days after the date shown on the Semi-Annual Groundwater Extraction Statement. Payments shall be made with credits, if available. The Board may extend the 30-day time allowed to pay surcharges for a period of up to twelve months when circumstances exist that in the opinion of the Board warrant such extension. The Board may also approve the payment of surcharges in installments of up to 24 months with terms suitable to the Board Late Penalty - The operator shall pay a late penalty for any extraction surcharge not satisfied by the due and payable date. The late penalty shall be 1.5 percent per month, or any portion thereof, of the amount of the unsatisfied extraction surcharge. The late penalty shall not exceed 100% of the original surcharge, provided the penalty is paid within 60 days of billing. If the fee is not paid within the 60 days, the penalty will continue to accrue at 1.5 percent per month with a final maximum of 200% of the original penalty due. 21

146 Collection of Delinquent Extraction Surcharges and Late Penalties - The Board may order that any given extraction surcharge and/or late penalty shall be a personal obligation of the operator or shall be an assessment against the property on which the extraction facility is located. Such assessment constitutes a lien upon the property, which lien attaches upon recordation in the office of the County Recorder. The assessment may be collected at the same time and in the same manner as ordinary ad valorem taxes are collected, and shall be subject to the same penalties and the same procedure and sale, in case of delinquency as provided for such taxes. All laws applicable to the levy, collection and enforcement of ad valorem taxes shall be applicable to such assessment, except that if any real property to which such lien would attach has been transferred or conveyed to a bona fide purchaser for value, or if a lien of a bona fide encumbrance for value has been created and attaches thereon, prior to the date on which the first installment of such taxes would become delinquent, then the lien which would otherwise be imposed by this section shall not attach to such real property and an assessment relating to such property shall be transferred to the unsecured roll for collection Use of Extraction Surcharges and Late Penalties - Revenues generated from extraction surcharges and late penalties shall be used exclusively for authorized Agency purposes, including financial assistance to support Board approved water supply, conservation, monitoring programs and water reclamation projects that demonstrate significant reductions in overdraft. CHAPTER 6.0 Appeals 6.1. Any person aggrieved by a decision or determination made by the Executive Officer may appeal to the Board within forty-five (45) calendar days thereof by filing with the Clerk, or Deputy Clerk, of the Board a written request that the Board review the decision of the Executive Officer. The Board shall equitably act on the appeal within 120 days after all relevant information has been provided by the appellant. CHAPTER 7.0 Severability 7.1. If any section, part, clause or phrase in this Ordinance Code is for any reason held invalid or unconstitutional, the remaining portion of this Ordinance Code shall not be affected but shall remain in full force and effect. 22

147 CHAPTER 8.0 Penalties 8.1. Any operator or other person who violates the provisions of this Ordinance Code is subject to the criminal and civil sanctions set forth in the Agency s enabling act and its Ordinances Any person who intentionally violates any provision of this Ordinance Code shall be guilty of an infraction and may be required to pay a fine to the Agency in an amount not to exceed five hundred dollars ($500) Any person who negligently or intentionally violates any provision of this Ordinance Code may also be liable civilly to the Agency for a sum not to exceed one thousand dollars ($1,000) per day for each day of such violation, in addition to any other penalties that may be prescribed by law Upon the failure of any person to comply with any provision of this Ordinance Code, the Agency may petition the Superior Court for a temporary restraining order, preliminary or permanent injunction, or such other equitable relief as may be appropriate. The right to petition for injunctive relief is an additional right to those, which may be provided elsewhere in this Ordinance Code or otherwise allowed by law. The Agency may petition the Superior Court of the County to recover any sums due the Agency. This Ordinance Code and amendments hereof shall become effective on the thirty-first day after adoption. 23

149 ORDINANCE NO. 8.3 An Ordinance to Amend the Fox Canyon Groundwater Management Agency Code The Board of Directors of the Fox Canyon Groundwater Management Agency ordains as follows: SECTION ONE: Section 1.27 of Chapter 1.0, Definitions, is hereby repealed and reenacted as follows: "Flowmeter" means a manufactured instrument for accurately measuring and recording the flow of water in a pipeline. SECTION TWO: Section 1.45 of Chapter 1.0, Definitions, is hereby repealed and reenacted as follows: "Well Flushing" means the act of temporarily discharging extracted groundwater through a connection located upstream of the water distribution system at the beginning of an extraction cycle. Well flushing is typically performed until the quality of the extracted water is suitable for beneficial use and/or will not damage the distribution system. In some cases, the flushing flows may be discharged upstream of the distribution system, including the flowmeter. Flushing flows discharged upstream of the flowmeter shall be estimated and reported to the Agency in accordance with the requirements accordance with the requirements in Chapter 2 of the Ordinance Code. SECTION THREE: Section 1.46 of Chapter 1.0, Definitions, is hereby added to the Ordinance Code as follows: "Well Rehabilitation" means the act of restoring a well to its most efficient condition by various treatments, development, or reconstruction methods. In most cases, groundwater extracted during well rehabilitation is not discharged through the extraction facility piping and, consequently, is not flowmetered. In these cases, the volume of water extracted shall be estimated and reported to the Agency in accordance with the requirements accordance in Chapter 2 of the Ordinance Code. SECTION FOUR: Section 1.47 of Chapter 1.0, Definitions, is hereby added to the Ordinance Code as follows: "West Las Posas Basin" is that part of the former North Las Posas Basin that is west of the subsurface anomaly described by significant changes in groundwater levels as described in the Groundwater Management Plan and located for record purposes on maps as provided in Section SECTION FIVE: Section 2.3 of Chapter 2.0, Registration of Wells and Levying of Charges, is hereby repealed and reenacted as follows: Page 1 of 4

150 2.3. Reporting Extractions - All extractions shall be reported to the Agency. All extractions shall be flowmetered in accordance with the requirements and methods for flowmetering extractions as specified by Chapter 3. In cases where flowmetering is not required, the volume of water extracted shall be estimated and reported to Agency. The Agency shall send a "Semi-Annual Groundwater Extraction Statement" form to each well operator on or about the first week of January and the first week of July each year. Each operator of a registered extraction facility shall enter the necessary information and return the "Semi Annual Groundwater Extraction Statement" covering all wells they operate on or before the due date. Statements are due on or before February 1 st or August 1 st annually or thirty days after the date of the letter requesting submittal of the Semi-Annual Statement for the given period. Statements shall contain the following information on forms provided by the Agency: The information required under Section above The method of measuring or computing groundwater extractions The crop types or other uses and the acreage served by the extraction facility Total extractions from each extraction facility in acre-feet for the proceeding six (6) month period. SECTION SIX: Chapter 3.0, Installation of Metering Equipment for Groundwater Extraction Facilities, is hereby repealed and reenacted as follows: CHAPTER 3.0 Installation and Use of Flowmeters for Groundwater Extraction Facilities 3.1. Installation and Use of Flowmeters Installation Requirement - Prior to extracting groundwater, the operator shall install a flowmeter. With the exception of connections used for well flushing and extraction facilities used by multiple operators, flowmeters shall be installed upstream of all connections to the main discharge line. Flowmetering is not required during well flushing and well rehabilitation; however, the volume of water extracted shall be estimated and reported to the Agency. Flowmeters are not required on inactive wells as defined in this Ordinance Code, nor are flowmeters required for extraction facilities supplying a single family dwelling on one acre or less, with no income producing operations. If more than one operator uses the same extraction facility, flowmeters shall be installed to record the water use of each operator. Well operators were required to install flowmeters on wells by July 1, Page 2 of 4

151 Flowmeter Failure and Back-up Measurement Requirements - Flowmeters occasionally fail, losing periods of record before the disabled or inaccurate meter is either replaced or repaired. When a flowmeter fails, the operator shall repair or replace the flowmeter within the timeframe specified in a separate Resolution. Flowmeter failures and associated repairs or replacements shall be reported to the another acceptable method of computing extractions during these periods of flowmeter failure to avoid the loss of record on wells that require flowmetering under this Ordinance Code Agency together with any other information required by the Executive Officer on or before the due date of the next Semi-Annual Groundwater Extraction Statement. Well operators shall be prepared to provide Back-up Methods - It is the operator's responsibility to maintain the flowmeter. Any allowable or acceptable backup measurement methods will be specified in a separate Resolution and may be changed as technology improves or changes Flowmeter Readings - Functional flowmeters shall be read and the readings reported semi-annually on the extraction statements required under Section 2.3 above Inspection of Flowmeters - The Agency may inspect flowmeter installations for compliance with this Ordinance Code at any reasonable time Flowmeter Testing and Calibration - All flowmeters shall be tested for accuracy at a frequency interval determined by the Board to meet specific measurement standards. Calibration methods and procedures approved by the Board shall be detailed in an adopted Resolution Altering Flowmeters - Any person who alters, removes, resets, adjusts, manipulates, obstructs, or in any manner interferes or tampers with any flowmeter affixed to any groundwater extraction facility required by this Ordinance Code, resulting in said flowmeter to improperly or inaccurately measure and record groundwater extractions, is guilty of an intentional violation of this Ordinance Code and will be subject to any and all penalties as described in Chapter Costs of Testing and Calibration - All costs incurred with flowmeter testing or calibration shall be the personal obligation of the well owner. Non-compliance with any provision of the flowmeter calibration requirements will subject the owner to financial penalties and/or liens as described below or in Chapter 8 of the Ordinance Code Fees and Enforcement - If any water production facility within the Agency's boundaries is used to produce water without a flowmeter or with a non-operating flowmeter in excess of the allowable timeframe specified in a separate Resolution, the Agency shall assess a Non-Metered Water Use Fee against the water production facility owner. The amount of the fee shall be calculated as follows: Page 3 of 4

152 3.5.1 Groundwater extraction facilities - The fee shall be equal to double the current groundwater extraction charge for all estimated water used. Estimates of water used shall be calculated by the operator and approved by the Executive Officer. Any delinquent extraction charge obligations shall also be charged interest at the rate of 1.5 percent per month on any unpaid balances Upon violation of any flowmeter provision, the Agency may, as allowed by law, petition the Superior Court of the County for a temporary restraining order or preliminary or permanent injunction prohibiting the well owner from operating the facility or for such other injunctive relief as may be appropriate.
